POSSIBLE CAUSES
Controller
 Shorted field F1 to F2
 F1 or F2 terminals shorted to battery
positive (B+)

Confirm that all inductive
loads/accessories are suppressed.

Motor armature or field shorted to
frame.
Defective control.

Replace controller unit.

CAUSE OF STATUS INDICATION
This status code will be displayed when the field
transistor exceeds its current limit. The line
contactor will drop out and the key switch will have
to be recycled to restart the control.
